A/N: Had the urge to write another action chapter, which means Aaaaaagent P! This is my take on how the boys eventually find out about Perry... again. I might write a 'follow up' chapter to this if people want it bad enough.

Re-Discovery

It had all happened so fast. Things had been fine. The day had been normal. But that was how these situations always were. It wasn't something you could expect to happen and plan for. Most individuals assumed it would never happen to them or to anyone they knew. Especially not anyone they loved. Even if the individuals evaded the norm almost every day with lives that were filled with a consistent rush and an endless supply of adventure and impossibilities.

Which was why the paralyzed feeling that gripped Ferb felt so out of place as he watched the delivery truck peel away from the curb side.

With his brother in the back.

Ferb hadn't initially realized when his brother was no longer beside him, singing for packages much like they always did. It hadn't registered in his brain that the man had grabbed hold of Phineas' shirt sleeve along with the clip board. That Phineas himself had been too surprised by the move to counter it. He recalled another hand from the back of the truck reaching for his own arm, but his reflexes were fast enough that he side stepped the glove, his heel hitting the curb and causing him to fall back into the grass. Ferb hadn't processed what was happening until the truck door closed, its occupants deciding not to waste any more time with the fallen brother. Apparently one was enough.

The green haired boy stumbled into the street in a desperate attempt to run after the vehicle. His brain knew he couldn't catch a truck on foot, but his heart refused to listen. An all-encompassing fear squeezed the breath from his lungs, released from his lips with a broken, strangled cry as he watched the truck get farther and farther away.

Ferb was quickly starting to hyperventilate, his fingers grasping his hair as his mismatched eyes darted wildly in thought of what he was supposed to do next. How he was supposed to handle this. What method would be the most efficient in bringing his brother back.

His panicked thoughts were interrupted by the sound of a revving engine close enough behind him that he subconsciously moved to the side. Looking over his shoulder, he watched as their driveway… opened up?

The cement slid aside, revealing a ramp leading from somewhere under their house. And even though their home had several mechanisms that moved the entire building up, down, and side to side, this addition to the driveway surprised Ferb.

Because he hadn't made that modification.

A flash of turquoise and white darted out from the tunnel, flying through the air and landing directly in the center of the street. The smell of burning rubber hit Ferb's senses as the custom motorcycle sped past him in the direction the truck had gone.

The thirteen year old was aware the amount of stress he was currently under and that the situation may be affecting his mind… but he could have sworn he saw a platypus tail flapping in the wind off the back of the bike.

Phineas gripped the sleeve of the arm wrapped around his shoulders, half trying to pull away from it and half trying to keep his balance with the violent motion of the truck. He wasn't incredibly sure what was going on. He was being kidnapped, he gathered that much. There was another man in the back of the truck with the one who currently had a tight hold on him. Only the one holding him was dressed as a delivery man, the other wearing jeans and a black t-shirt. Phineas didn't recognize either of them.

"-he was RIGHT next to this one! You couldn't have just grabbed him?!"

"He stepped out of the way! And then Jeff gunned it!"

Judging by their conversation though, it wasn't a very well thought out kidnapping.

"Uuum," Phineas tried to ask what was going on, but the men were shouting at one another and to whoever was driving the truck. Apparently that was Jeff. It seemed rude to try and speak over them. Though he had always been raised to be polite and understanding, perhaps this wasn't a situation where he should be concerned about manners. It was never easy for a child like Phineas, who liked to see the best in everyone, to take off his rose colored glasses and remember not everyone was the best.

"-he'll alert the police and then we'll have them putting out an Amber Alert before the agent even knows we have one! This was supposed to be done discreetly!"

The man holding him was upset that his partner hadn't caught his brother, for which Phineas was grateful for. But he would be lying to himself if he didn't admit that he was also unnerved by the fact that he was alone with people who obviously didn't have his best interests in mind. And an agent? Agent of what?

"Then we'll dump him and check back with the organization."

Phineas swallowed thickly. He really hoped that didn't mean while the truck was still moving.

Said truck made a sharp turn, clipping the curb and jostling the occupants of the back cargo hold. It was enough to knock one of the men into a few of the cardboard boxes and the other to loosen his grip on Phineas. The red head took advantage of that fact and shoved away from the man. But other than move a few feet away beside some of the boxes or through to the connecting front cab with the driver, Phineas had nowhere to retreat to. He pressed himself up against the farthest wall from his captors.

"Watch your driving! We've got nothing to hold onto back here!" the fallen man struggled to right himself.

"That's the least of our worries right now," the driver barked back at them.

The two other men looked at each other quizzically, but their answer was given in the form of a loud bang against the back door of the truck. Phineas jolted at the sound, turning to look as well and seeing the metal at the corners of the door dented in. Another bang blew the hinges off at the door, one side flying open. The force of the wind and the speed of the truck ripped the rest of the loading door off, causing the passengers to scramble to the back of the truck.

Fear rippled through Phineas at the sight as he pressed himself against the wall as much as he could; palms and cheek up against the cold metal. He looked out the now open end of the truck, watching the door hit the road and almost hit a motorcyclist who was driving behind him. But the cyclist expertly dodged the flying sheet of metal, speeding up to get closer to the truck. It took Phineas a second to realize the cyclist wasn't just driving behind them. He was following them. And judging by the lasers attached to the side of the bike, he was probably the reason the truck had no back loading door anymore.

For a moment, Phineas' heart leapt at the thought of rescue. But the closer the bike got, the more the red head squinted his eyes to make out the details of the driver. Looking past the bike's windshield and the driver's helmet, elements of the cyclist didn't make sense to Phineas.

And yet, at the same time, they made complete sense to his subconscious.

A duck bill.

Webbed back feet.

A beaver tail.

Phineas immediately blamed fear and insanity. The stress of such an ordeal was getting to him, that was all. It couldn't and shouldn't be what it looked like. It didn't make any sense. But then again, the entire situation made little sense. Perhaps he was dreaming. Because only in a dream world would he be kidnapped by unknown men and then pursued by-

"How the hell did he get on us so fast?!"

"I told you we didn't have a lot of time! He works fast!"

The man in the black shirt got his balance back, reaching over to grab the back of Phineas' shirt, making the boy yelp. He was pulled away from the relative safety of the truck wall and forced in front of his captor. "N-no! Stop!" He reached back to try and wretch the collar of his shirt from the man's gloved grip, terrified as he was moved closer and closer to the open door. He dug his heels in, trying not to picture himself coming to the same end as the loading door. His situation didn't improve any when the man's free hand pulled a gun from the waistband of his jeans.

Phineas inhaled sharply at the sight of the weapon being pointed at the cyclist. The logical side of the boy's thought process still wasn't completely convinced that the owner of the motorcycle was who it appeared to be. But seeing the gun pointed at the short furry driver almost seemed to flip a switch in Phineas' brain.

Broken images flew through his mind, clips and memories of fedoras and robots that shouldn't be there. They had no context. But the feelings the boy had when they flashed across his vision were as if he was waking up from a deep, vivid dream. The memories started out fuzzy and indecipherable, but with each image came more clarity. More detail.

Frightened blue eyes met a narrowed brown gaze through the motorcycle visor.

The gun went off; the bullet ricocheting off the fiberglass shell of the motorcycle as it just missed its target.

"PERRY!"

The motorcycle sped up to drive beside the truck and out of firing range, giving Phineas a chance to catch the breath he hadn't known he was holding. The name had slipped past his lips as naturally as it would if he had known exactly what was going on. Because all at once he did know. He struggled as the man wrapped his arm fully around his body, pinning his arms to his sides, "Don't shoot him! Please don't shoot him!"

The boy's desperate pleas were ignored, the man holding him shouting back to his partner in the delivery guy disguise. "Are they far enough away or what?"

The other man was checking a cell phone as he braced himself against the wall for stability. "They want us to distract the agent as long as we can."

"Easy for them to say! If this guy catches us, he's going to rip out our spines for touching this kid!" the man in black hissed, gesturing to Phineas with the barrel of his gun. The boy winced, tensing up as the weapon was moved closer to his face. He was trying hard to balance his fear and understand what was going on, while also make sense of the unknown memories filtering through his brain. Why did it suddenly make sense that his beloved pet had this secret life? Why did he both know it to be true and yet was surprised by it at the same time? Another loud bang sounded, this time on top of the truck.

Phineas' heart leapt into his throat at the sight of the motorcycle coming back into view behind the truck and slowing to an automated stop. Without anyone driving it. The boy was momentarily convinced that Perry had fallen from his bike, but the sudden shout from Jeff the driver made it a little more clear what had happened.

"I need some help up here!"

The two men turned around, the one holding Phineas yanking him off his feet and tucking him under his arm as if he were a football. Sure enough, they could see through the little doorway that there was a platypus now inside the cab of the truck. Jeff was driving with one hand while trying to keep the monotreme from grabbing the wheel with his other.

The delivery man in disguise rushed through the doorway into the cab, making a grab for the agent only to get a turquoise punch to the face that knocked him into the passenger seat.

Agent Perry the Platypus growled in warning as he balanced himself on the dashboard, glaring down his opponent. He was beyond livid and it showed in his brown eyes. He didn't know how L.O.V.E.M.U.F.F.I.N had gotten enough intel to connect Phineas and Ferb to him and he wasn't sure how that would affect his entire way of living. But he would worry about it later. He had a hunch that after singlehandedly taking down several of their latest schemes, the organization realized it wasn't going to get anything done unless top level O.W.C.A Agent Perry the Platypus was thoroughly distracted.

He knew the league was working on something big, Major Monogram having been debriefing him when he had heard the boys' shouting. He had switched the monitor on his computer screen to the cameras in the front yard, seeing one of his owners pulled into the back of a delivery truck. Suddenly whatever mission he was being given paled in comparison to his boys' safety. Ignoring the Major's insistence that he stay put, Perry was off like a shot. He hadn't expected the two sides of his life to intersect that morning. It was the fodder that made up his nightmares.

Perry never anticipated this sort of thing from Doofenschmirtz. The man was a father himself after all. And the evil scientist was helping his daughter move to college that weekend. But Perry didn't put it past some of the other members of L.O.V.E.M.U.F.F.I.N to resort to kidnapping. After all, one of the members was completely willing to send the entire planet into a new ice age. And though he had always worried about this exact situation happening, the agent hadn't counted on just how furious it would make him.

Perry dodged a swipe from the driver and jumped down to the floor. The man in the passenger's seat tried to bring his boot down on the platypus, but Perry rolled out of the way. Instead his boot hit the emergency break, snapping it in half. The driver glared at his partner.

"What the hell Dave! Seriously?!"

Perry ducked as a bullet zipped right over his fedora and into the consol, taking out the GPS navigation.

"What the hell Tom?! SERIOUSLY?!"

Phineas kicked his sneaker at the man holding him, scraping down his shin and adding to Tom's flustered state from having missed his target. He winced and dropped the boy, driving his boot into Phineas' side. The twelve year old cried out, pushing himself back away from the man who turned his gun on Phineas instead. "Don't go getting any ideas, kid, or I'll-"

A tangerine beaver tail came down hard on the man's hand holding the gun, making him drop it. The weapon clattered to the floor of the truck and slid towards the open back. Perry landed in a crouch between Tom and Phineas, chittering angrily. The man had already broken the cardinal rule of laying a hand on one of his boys. He'd signed his own death sentence by pointing a gun at him.

Tom swallowed hard, his eyes darting between the irate monotreme and the fallen weapon. In a split second decision, he made a lunge for the gun. He soon realized it had been the wrong decision when a webbed foot came down hard between his shoulder blades, knocking him off balance. He missed the weapon and fell forwards. Perry jumped off the man's back and landed on a tower of boxes, watching as Tom fell head over heels out of the truck.

"Perry!"

The agent looked back over his shoulder, seeing Delivery Guy Dave grab Phineas' wrist, yanking him off the floor. The man pulled the child against his front, his other hand taking a box cutter out from his pocket. Phineas froze, ceasing his struggles as the blade was held against his throat.

Perry fought down the welling emotions building up at the sight of his boy in such a state, keeping his perched stance on top of the boxes. He took the hint, staying still and not getting any closer.

Dave looked away from the platypus' glare, the scenery out the back of the truck catching his attention. They weren't where they were supposed to be. "What are we doing at the docks?!"

"I don't know!" Jeff shouted back, gripping the wheel. "Tom's idiocy took out the GPS! Nice going, Tom!"

"Tom fell out of the truck," Phineas said, keeping his eyes on the blade just under his chin.

"Really?" Jeff flinched. "Man, I kinda feel bad now."

"Just shut up and dri- hey where'd he go?" Dave looked back, finding there was no longer a platypus on top of the boxes.

"I thought the kid just said he-AH!"

The truck swerved as Jeff was startled by the sudden appearance of a platypus swinging down through his open window, receiving a webbed foot to the jaw. The movement threw about the occupants of the cargo hold, Dave and Phineas falling back into the boxes. The box cutter grazed Phineas cheek just under his eye when it slipped from Dave's grip. But the red head took no mind to the stinging as he scrambled to get away from his captor and avoid being tossed from the truck with each dangerous swerve. He found a coil of bungee rope bolted to the floor that was used to hold down bigger packages, clinging to it.

Jeff had lost control of the vehicle, his vision swimming after a particularly firm slap from Perry's flat tail. The platypus' heel came down on the handle of the car door, kicking it open as he gripped the seat belt. A firm shove to the side tossed the man out and placed Perry square in the driver's seat. He grasped the wheel finally, but cringed as he looked out the front window, seeing the end of the docks. The truck was headed right for the water. He reached for the emergency break, but grabbed nothing but air, cursing inwardly when he remembered its fate. He turned frantically in his seat, worriedly looking behind him and into the back of the truck. He scanned the area for his young charge, finding Phineas on the floor amongst the boxes.

Phineas looked up, making eye contact with the agent and seeing the unmistakable fear in Perry's eyes. A quick glance out the windshield made him inhale sharply, seeing the Danville Bay rushing up to meet them. There was only a moment for them to brace themselves.

The force of the impact threw Phineas forward into the boxes. Perry gripped the back of the seat's headrest, tensing his body as the water shattered the windshield and poured into the cab at an alarming rate. He only opened his eyes after the water had gone over his head, taking a split second to get his bearings. He looked back to the entrance into the cargo end of the truck, but it was blocked by all the boxes that had flown forward when they landed. His agile body twisted around in the water, darting out through the open car door window.

Perry moved through the water easily, swimming around the side of the truck as it sunk. Having no back door meant no trapped air, causing the vehicle to sink fast. He pushed through boxes as he looked up at the lighted, rippled surface of the water, seeing Dave swimming towards the waves. Perry looked around amongst the floating boxes, desperately hoping to see the red head kicking for the surface as well. But when he reached the back of the truck and there was no sign of his boy above him, Perry looked back into the darkened cargo hold.

Phineas had gotten tangled in the bungee rope, frantically trying to pull against the coils as they dragged him down with the truck. He turned wide, terrified eyes up to the surface; Perry's darkened form swimming towards him as fast as a platypus could.

When their eyes met, Perry wished he could tell him that it would be alright. To reassure him that he was coming. That he needed to stay calm and not struggle. His tail beat the water rapidly, sending him inside the truck in record time. Perry caught a glimmer of light out of the corner of his eye, the box cutter wedged in the corner of the truck's doorway. He snatched the weapon and swum up beside his owner, giving him a encouraging look as he got to work cutting the ropes. He could see the boy struggling to hold his breath; his eyes squinted as he did his best to hold on.

Perry sliced the last of the ropes as a torrent of bubbles burst from Phineas's nose and mouth. He quickly grabbed his boy's wrist as his body powered through the water, built especially to do so. He could feel the burn in his own chest, but was focused solely on getting Phineas' head above the water. When they broke the surface, Perry was relieved to hear the boy coughing, but quickly realized he wasn't getting much air in as he tried to expel the water from his lungs.

The agent strained to keep the boy up high enough so the waves wouldn't add more water into the gasping child. Phineas was twice his size, but years of training made him strong. And his worry for his boy made him stronger.

They made it to the shallows, a rocky beach beside the harbor. Phineas was wheezing heavily, but finally getting enough air in as he weakly treaded water with one arm, letting Perry do the majority of the swimming until his sneakers scraped against the sandy bottom of the shore. Once they were only in a few inches of water, the red head collapsed to his hands and knees, not caring about the tiny rocks digging into his skin as he hacked and sputtered. A surge of water and bile spilled from his lips, making his eyes water. Phineas focused on slowing down his breathing, bringing up a shaky hand to wipe the moisture from his eyes and face. He felt a hand on his back and shoulder, gently rubbing between his shoulder blades in a calming manner. As soon as he was able to take in a steady and full breath, he looked up at the agent.

Perry, sans his hat, was staying close, waiting for Phineas to show him he was alright. When the boy sat back fully the monotreme was quick to check him over, his little paw on his cheek and frowning at the cut below his eye. "I-I'm okay," Phineas tried to clear his raw throat. "J-just wet," he half laughed awkwardly, coaxing a small smile from his pet.

Perry exhaled softly, thankful as he shared a quiet, locked gaze with his owner. Now that he was't worried he would have to rush the twelve year old to the hospital, he was trying to gauge where Phineas was at emotionally. There was no denying his secret was out… again. But it was a stark difference from the first time Phineas learned of his double life almost two years ago. There was evil megalomaniac getting into his head, trying to spin his alter ego in a poor light. But Perry could still remember how hurt the boy had been, that look of betrayal was burned deep into his memory banks. Phineas' scathing words. Perry had never wanted the ability to speak so badly. And here he was again, bracing himself for the judgmental outburst. Waiting for the boy to tear into him and demand answers. He had every right to. He'd been unwilling dragged into this and had been nearly killed because of it.

But the outburst never came.

Phineas finally broke eye contact and looked down at his lap as he swallowed, letting his saliva try to soothe his sore throat. It was a lot to take in. And he was grateful for the platypus beside him, a firm but gentle paw on his shoulder, still gently rubbing circles to calm him from the stressful ordeal. He recalled once feeling a different set of emotions, ones linked to the confusing memories that swirled in his brain. He remembered being so angry. Feeling so betrayed at being lied to. Feeling like he never mattered.

But at that moment, he couldn't possibly feel any of those things. It was clear how important he was to the agent. He closed his eyes when he felt Perry brush aside his wet bangs, trying to coax a response out of him. He should be questioning everything that had just happened to him and why. Why he was remembering things he wasn't even sure had actually happened but seemed so real. The words spilled out before he had a chance to think them over.

"I know about all of this already, don't I?"

Perry blinked, not expecting that to be the response. He removed his hand from the boy's hair, chewing on the lower portion of his bill in worry.

"This… happened before, didn't it? Well… well not like this exact thing but… But something like it. Right?" Phineas finally looked up at him.

Perry stared at him a moment before sighing and slowly nodding. Phineas' memories from the alternate dimension escapade were surfacing. He had always been worried if there would be any side effects to the Amnesia-Inator. He hadn't counted on this being one of them.

The tide washed against them slowly, spilling over Phineas' lap and at Perry's feet and tail. Both of them looked down as the small waves brought with them a soaked 1940s fedora. The brim gently bumped against Phineas' knee and he carefully eased it out of the water, holding it in both his hands.

"…I'm not supposed to know, am I?" he asked, staring down at the hat.

Perry looked away; back out at the water where the trunk had driven off the dock. Phineas looked over to the spot as well, boxes still floating out in the bay.

"Yeah… I guess it's pretty obvious why."

Both were quiet for a long moment before police sirens in the distance broke them from their trance. Phineas sighed and looked back at Perry. The platypus still looked like he was expecting a lecture. But what he received was anything but. He tensed suddenly when Phineas reached forward to hug him.

"…. Thanks buddy."

Perry's body slowly relaxed, encircling his arms around the boy to return the gesture, utterly thankful he was okay. He wasn't exactly sure how O.W.C.A was going to handle all this. If Phineas had retained some of his memories, it meant the Amnesia-Inator wasn't a full proof option. And there was no way in hell he was ever leaving his boys. It just wasn't a threat he took seriously from the organization anymore, because he would quit before he would let it happen. His job was important… but Phineas and Ferb were even more so. Perry decided they would cross that bridge when they drove a truck off it. Right now he was sure the rest of their family was sick with worry.

Phineas pulled himself to his feet and out of the water, albeit with shaky knees. "So…" he flipped the fedora around in his hands, admiring the worn leather. Printed letters on the inside made the red head smile. "Agent P, huh?"

Perry smirked with a small salute, his other arm around the boy's side to keep him steady as they waded out of the water and onto the beach. "Well…" Phineas plopped the wet hat back onto the platypus' head. "What happens now, Agent?"

Perry pulled out a soggy pamphlet and handed it to Phineas as they walked up the beach. The boy looked down at the O.W.C.A insigna across the front, another memory of the same paper flashing though his mind.

He smirked, wadding up the soaked paper and tossing it over his shoulder. "I don't want your pamphlet."

The agent chattered in response, shaking his head and rolling his eyes. He should have figured that much would stay the same.
